We did a fairly extensive rundown of eBooks for the iPhone/iPod touch in August; you can take a look back if you're new to the eBook universe for Apple's mobile devices.

BookReader [iTunes Link] , a US$4.99 app for devices running OS 2.21 or higher, has just joined the crowded eBook market -- but it brings little to the table to recommend itself. The app when first run looks beautiful. You are shown a wonderfully rendered bookshelf which looks very similar to the one found in Classics [iTunes Link], but a bit more nicely rendered, showing the spines of books instead of covers in a scrolling list.

Impressive, but now what? I really had no idea since there were no instructions on how to operate the app either in the app, or on the Readdle site. This, as I've often said, is a major downfall of many of the apps in the store. It would be fine if it were an adventure game, but not at all acceptable in something offering utility that you would like to get at quickly.

The only documentation in the app is a cursory explanation of one of three methods of getting content into the app -- connecting via Wi-Fi and WebDAV to your computer in a fairly arcane manner. You connect to an external server and provide an app-created numeric password. From there you can add books to the server folder... or so they say, but they don't go as far as saying how. I added books to the server, and they never showed up in the app. I was left stranded on the Wi-fi access page and didn't know where to go from there. Now I know that I'm missing something minuscule, but that's exactly my point; there wasn't enough given to me to allow me to complete the task.

The second method of acquiring content is through Readdle Storage. You need to set up an account on the Readdle site which gives you a free 512 megabytes; larger amounts of storage are available for purchase. Once you set up an account, it works fine, but unless you know what to do, you may not find it on your own. You can easily add documents to Readdle Storage and they do show up in the app.

Many documents, unfortunately, don't look very attractive. Anything that started as a .pdf document winds up looking like garbage since all the graphics are gone, and the formatting is stripped out. The list of formats that BookReader handles is also lacking. It doesn't understand some very popular formats such as Kindle, MobiPocket and Microsoft Word's .DOC as do other apps such as Stanza [iTunes Link]. DRM is not supported, but that's par for the course in the eReader market.

An e-book (or ebook, or eBook, depending upon who you ask) is the digital equivalent of a paper book. According to KiwiTech, the publishers of Classics2Go, the market for eBooks has increased more than 60% over the last six years and growth from this point is expected to be very strong.

We can reasonably connect the start of this burgeoning market to the release of the Amazon Kindle in 2007. Strong sales convinced some wary readers that this was a viable option. You could carry a few hundred books under your arm, and the reading experience was, well, acceptable. Going on a long trip? Wouldn't it be nice to take about 20 pounds of paper out of your luggage?

2007 also marked the introduction of the iPhone; it took about a year for eBook apps to appear on the iPhone. Now there are so many of them that finding the right one for your purposes can be a confusing prospect. I would like to clarify all this a bit by categorizing the four types of eBook apps, at least so far, and letting you know what you can expect from each.

In deciding upon an eBook reader you need to consider: what sort of material you will be reading, how much you are willing to spend (if anything) and the quality of the viewing experience.

Last year, Andrew Kazmierski and Phill Ryu released Classics (iTunes link). Their idea was to take a bunch of books in the public domain, 22 in the current release, and control all aspects of the user experience. We covered the first release of Classics upon its original release when its price was $2.99. Since then, the price has dropped to .99 and the number of books has increased.

This app looked so impressive that it was featured in an Apple iPhone commercial. Upon launch, the reader is presented with a nicely rendered wooden bookshelf displaying colorful dust jackets. Click on a book and start reading. There is no wait, since all the books were downloaded with the app. Future updates bring more books. The books are all the kind of classics that are on school reading lists ranging from Frankenstein and Dracula, to Hound of the Baskervilles.

The feature set is slim. Tap the right side of the screen or swipe right to left and the sepia toned pages turn using a pleasing animation. There are two buttons on the top of the screen. One brings down a maroon and gold bookmark and sends you to the bookshelf. When you click on the book again, you are brought to where you left off. The second button takes you to a table of contents. The bottom of the screen tells you the name of the chapter you are reading and what page you are on. The top of the screen displays the title of the book. Illustrations in books like Alice in Wonderland are nicely rendered, and the text is attractively formatted. A change in color of the title bar gives you an idea of where you are in the book.

Eucalyptus [App Store] has been finally allowed to appear in the App Store after being rejected by Apple. The e-book reader for the iPhone and iPod touch was rejected because a person could get sexually oriented books like the Kama Sutra, even though the book is in the public domain and freely available on the web.

The program author let us know the US$9.99 app was approved late last night. He said, "Earlier today I received a phone call from an Apple representative. He was very complimentary about Eucalyptus. We talked about the confusion surrounding its App Store rejections, which I am happy to say is now fully resolved. He invited me to re-build and submit a version of Eucalyptus with no filters for immediate approval, and that full version is now available on the iPhone App Store."

"Since my previous post, I've been so pleased with the overwhelmingly positive articles, blog posts, comments and tweets - and also the emails from those of you who felt so strongly about the issue you wanted to contact me directly. They were all much appreciated. Thanks for all the support. It's been a roller coaster of a weekend!"

The controversy over this app once again points out how crazy the Apple standards for applications are. Dozens of fart apps are fine (not to mention apps that thoroughly infringe other companies' IP or steal their graphics) but an e-book reader that simply loads public domain books was verboten. It doesn't make any sense, and further, the situation doesn't seem to be improving. Developers are left to try and get publicity to embarrass Apple into being a bit more sensible.
